At the end of each Act, you will encounter a powerful boss enemy that is selected randomly from three possible options exclusive to that Act. The preceding space on the map will always be a Camp Fire, allowing you to rest before the fight. Defeating a boss rewards you with big amounts of gold, a rare card and a choice of three Boss Relics, after which you progress to the next Act with full health (unless you're playing on higher levels of Ascension mode).
